Fig. 1 is a block diagram of a vehicle display error detection system 1000 according to some embodiments of the present disclosure. In some embodiments, the in-vehicle display debugging system 1000 includes an in-vehicle system 1100 and a display system 1200. The in-vehicle system 1100 is coupled to the display system 1200. In some embodiments, vehicles equipped with on-board display debug system 1000 include gasoline vehicles, hybrid gasoline vehicles, and electric vehicles having multiple display screens.

In some embodiments, the in-vehicle System 1100 comprises a System on a Chip (SoC). The system-on-chip comprises a multifunctional chip.

In some embodiments, the on-board system 1100 is configured to compile driving information of the vehicle to calculate vehicle information provided to the driver thereby. The driving information of the vehicle includes the amount of oil stored in the oil tank of the vehicle, the rotation speed of the engine of the vehicle, the display control of the display system 1200, and the states of the vehicle sensors.

In some embodiments, the display system 1200 includes a timing controller 1210, a first display 1220, a first driving circuit SIC1, a second driving circuit SIC2, a first gate driving circuit GOA1, a second display 1230, a third driving circuit SIC3, a fourth driving circuit SIC4, and a second gate driving circuit GOA 2. In some embodiments, the first gate driving circuit GOA1, the first driving circuit SIC1, and the second driving circuit SIC2 are coupled to the first display 1220. It should be noted that the number of displays of the display system 1200 is not limited by the embodiment of the drawings.

In some embodiments, the displays of display system 1200 include a dashboard liquid crystal display behind the steering wheel of the front driver seat, a liquid crystal display of the center console, a side window display near the front driver seat, a side window display near the front passenger seat, and a windshield display.

In some embodiments, the timing controller 1210 is coupled to the first display 1220, the first driving circuit SIC1, the second driving circuit SIC2, and the first gate driving circuit GOA 1. The first gate driving circuit GOA1 is used for driving the horizontal pixels of the first display 1220. The first driving circuit SIC1 and the second driving circuit SIC2 are respectively used for driving vertical pixels of the first display 1220.

In some embodiments, the timing controller 1210 is coupled to the second display 1230, the third driving circuit SIC3, the fourth driving circuit SIC4, and the second gate driving circuit GOA 2. The second gate driving circuit GOA2 is used for driving the horizontal pixels of the second display 1230. The third driving circuit SIC3 and the fourth driving circuit SIC4 are respectively used for driving vertical pixels of the second display 1230. It should be noted that each of the first driving circuit SIC1, the second driving circuit SIC2, the third driving circuit SIC3 and the fourth driving circuit SIC4 includes a source driving integrated circuit. The number of the source driver ics is not limited to the embodiments shown in the drawings, and the display size is designed, for example, a 23-inch display may be equipped with four source driver ics.

In some embodiments, the timing controller 1210 includes a Random Access Memory (RAM), a Data processor (Data processor), and an Integrated bus Circuit (I)²C) A processor or Serial Peripheral Interface Bus (SPI) processor, a finite state automaton (FSM).

In some embodiments, the timing controller 1210 is configured to receive a plurality of signals (e.g., the first error detection signal ASF1) of the first display 1220 and a plurality of signals (e.g., the second error detection signal ASF2) of the second display 1230. In some embodiments, the in-vehicle system 1100 is configured to transmit signals to and from the timing controller 1210 in two directions. It should be noted that the timing controller 1210 has signal transmission paths with the first display 1220 and the second display 1230, respectively, for bi-directionally transmitting the error detection signals or the control signals. It is further illustrated that the in-vehicle system 1100 also receives the error detection signal or the control signal from the timing controller 1210, the first display 1220, and the second display 1230.

Fig. 2 is a flowchart illustrating steps of a fault detection method 200 according to some embodiments of the present disclosure. In some embodiments, the debug method 200 can be performed by the on-board display debug system 1000 shown in fig. 1. Debug method 200 includes the steps described below.

In step 210, the vehicle is started. In some embodiments, vehicles equipped with the on-board display error detection system 1000 of the present disclosure substantially include a power supply system. The power supply system is used for providing power required by all electric devices or systems in the vehicle.

In step 220, whether an error detection signal is detected is determined. In some embodiments, referring to fig. 1 and fig. 2, the vehicle-mounted display error detection system 1000 is provided when a power system of a vehicle provides power to the vehicle. The in-vehicle system 1100 of the in-vehicle display error detecting system 1000 and the timing controller 1210 are configured to detect whether the first state of the display system 1200 is abnormal. When the first state of the display system 1200 is abnormal, the display system 1200 generates a debug signal (e.g., the first debug signal ASF1 or the second debug signal ASF 2). It should be noted that the timing controller 1210 and the first display 1220 transmit the first error detection signal ASF1 bi-directionally through a specific channel. The timing controller 1210 and the second display 1230 transmit the second error detection signal ASF2 bi-directionally with each other through another specific channel. The first error detection signal ASF1 and the second error detection signal ASF2 do not affect each other. If the error detection signal is detected, the in-vehicle system 1100 and the timing controller 1210 execute step 230. If the error detection signal is not detected, the in-vehicle system 1100 and the timing controller 1210 execute step 250.

Fig. 3 is a schematic diagram of a display screen of a display 1220 of the vehicle-mounted display debugging system 1000 according to some embodiments of the disclosure. In some embodiments, the first display 1220 includes a first display region a1 and a second display region a 2. The first display region a1 and the second display region a2 do not overlap each other. The first display area a1 and the second display area a2 are used for displaying the display screen P1 together. The gate driving circuit GOA1 is used to control the first display area a1 of the first display 1220 together with the first driving circuit SIC 1. The gate driving circuit GOA1 is used to control the second display area a2 of the first display 1220 together with the second driving circuit SIC 2. It should be noted that fig. 3 shows the first display 1220 in a normal display state. The size of the display screen P1 is not limited to the illustrated embodiment. The sizes of the first display area a1 and the second display area a2 are not limited to the illustrated embodiment. The positions of the gate driving circuit GOA1, the first driving circuit SIC1 and the second driving circuit SIC2 are not limited to the illustrated embodiments. Fig. 3 shows a first display 1220, namely an instrument panel lcd display, which is located at the front of the steering wheel.

In step 230, the emergency mode is switched to. In some embodiments, referring to fig. 1 and fig. 2, when the on-board system 1100 and the timing controller 1210 of the on-board display error detecting system 1000 detect an error detecting signal, the on-board system 1100 and the timing controller 1210 enter an Emergency mode (or called Emergency mode) to preferentially eliminate a fault condition of the vehicle or an abnormal first state of the display system 1200.

In step 240, classification is performed according to the error detection signal. In some embodiments, when the vehicle-mounted system 1100 and the timing controller 1210 receive the error detection signal and enter the emergency mode, the vehicle-mounted system 1100 classifies the abnormal first state of the display system 1200 according to the error detection signal to generate a control signal to cope with the abnormal first state, and adjusts the abnormal first state of the display system 1200 to be the normal second state of the display system 1200. It should be noted that, in the process of adjusting the display system 1200 by the in-vehicle system 1100, the in-vehicle system 1100 performs related operations on the display system 1200 by the timing controller 1210.

In some embodiments, to facilitate understanding of steps 240 to 243 of the error detection method 200 of the present disclosure, please refer to fig. 3 to fig. 11B together, and fig. 4, fig. 5, fig. 7, fig. 8, fig. 10A, fig. 10B, fig. 11A and fig. 11B are schematic display images of a display of a vehicle-mounted display error detection system according to some embodiments of the present disclosure. Fig. 6 and 9 are signal timing diagrams of a timing controller of an on-board display error detection system according to some embodiments of the present disclosure.

In step 241, the display screen or driving mode of the vehicle display is adjusted. In some embodiments, referring to fig. 3 and fig. 4 together, fig. 3 shows a first state of the display system 1200 being a normal display state. In contrast to fig. 3, the first state of the display system 1200 in fig. 4 is a display abnormal state, and in detail, the first display 1220 of the display system 1200 in fig. 4 is in a display abnormal state. Further, when the first state of the display system 1200 is the abnormal state of one of the first driving circuit SIC1 and the second driving circuit SIC2, one of the first display area a1 and the second display area a2 cannot present the display screen P2. Therefore, the in-vehicle system 1100 evaluates the first status of the display system 1200 to a predetermined level (e.g., a light damage level) according to the error detection signal. For example, the embodiment of fig. 4 is that the second driving circuit SIC2 is damaged, which results in that the second display area a2 cannot present half of the display screen P2.

In some embodiments, referring to fig. 3 and 5, after the first display 1220 is evaluated as a light damage level by the in-vehicle system 1100, the in-vehicle system 1100 generates a control signal and controls the first driving circuit SIC1 through the timing controller 1210 to zoom the display screen P1 of fig. 3 into the display screen P3 of fig. 5. The display frame P3 of fig. 5 is the modified frame of the first display 1220, i.e. the second state of the display system 1200. In some embodiments, the display P3 of FIG. 5 is a zoomed view of the display P1 of FIG. 3. In some embodiments, the display P3 of FIG. 5 is a scaled view or a non-scaled view of the display P1 of FIG. 3.

In some embodiments, referring to fig. 1 and 6, fig. 6 is a timing diagram of signals received and output by the timing controller 1210, which is a time when the timing controller 1210 drives the first driving circuit SIC1 or the second driving circuit SIC2 for one frame (frame). The time of a frame (frame) includes a first stage I1 when the display system 1200 is in the first state and a second stage I2 when the display system 1200 is in the second state. The signal Internal DE is a clock signal. The error detection signal ASF is the first error detection signal ASF1 or the second error detection signal ASF2 of fig. 1. The signal SD1 is a control signal output by the timing controller 1210 to the first driving circuit SIC1 and a display signal related to a display screen (for example, display screens P1 to P7 in the present embodiment). The signal SD2 is a control signal output by the timing controller 1210 to the second driving circuit SIC2 and a display signal related to a display screen (for example, display screens P1 to P7 in the present embodiment). The signal XSTB, the signal STV1, and the signal VCE are basic driving signals. The termination signal termination is a termination signal that the first state of the display system 1200 transitions to the second state.

It should be noted that the signal SD1 in the first phase I1 and the signal SD1 in the second phase I2 are different driving signals. The signal SD2 is in the first phase I1 and the signal SD2 is in the second phase I2. The sub-phase I12 of the first phase I1 and the sub-phase I21 of the second phase I2 are buffer phases for the transition of the first state to the second state of the display system 1200.

In some embodiments, referring to fig. 3 and fig. 7, fig. 3 shows the first state of the display system 1200 being a normal display state. In comparison with fig. 3, fig. 7 shows that the first state of the display system 1200 is a display abnormal state, and in detail, fig. 4 shows that the first display 1220 of the display system 1200 is in a display abnormal state. It is further described that when the first state of the display system 1200 is the gate driver GOA1 of the first display 1220 is abnormal, the first display area A1 and the second display area A2 are caused to display the display image P4 as shown in FIG. 7. Therefore, the in-vehicle system 1100 evaluates the first status of the display system 1200 to a mild damage level according to the debug signal.

It should be noted that the gate driving circuit GOA1 is used for driving and scanning the pixels of the first display 1220 through a plurality of gate lines arranged in a vertical direction (Y-axis direction in the drawing). The gate driving circuit GOA1 drives the gate lines Mth GL from the 1st GL row to the Mth row from above in the drawing. The total number of gate lines is M, where M is a positive integer. And the gate line Nth GL represents a gate line or gate lines that begin to be damaged in the Nth row. In some embodiments, the gate driver GOA1 includes a shift register or a plurality of shift registers, and the gate driver GOA1 may employ Gate On Array (GOA) technology. Two examples will be provided hereinafter as reference.

For example, N is now the 10 th row of gate lines damaged, and the total number of gate lines M is 720. The gate driving circuit GOA1 can only drive the 1st to 9 th rows of gate lines, i.e. the 11th to 720th rows of gate lines 720th GL cannot drive the pixels of the first display 1220, resulting in the first display 1220 displaying the display image P4 as shown in fig. 7.

For example, N is currently the 10 th to 20th rows of gate lines damaged, and the total number of gate lines M is 720. The gate driving circuit GOA1 can only drive the gate lines 1st GL to 9 th from the row 1, that is, the gate lines 21th to 720th from the row 720th GL cannot drive the pixels of the first display 1220, so that the first display 1220 displays the display image P4 as shown in fig. 7.

In some embodiments, referring to fig. 1 and 8, after the first display 1220 is evaluated as a light damage level by the in-vehicle system 1100, the in-vehicle system 1100 generates a control signal and controls the gate driving circuit GOA1 through the timing controller 1210 to change the driving mode. This driving mode is a top-down progressive scan. The driving mode is changed to a driving direction, and more specifically, the driving mode is changed to a bottom-up progressive scan to show the display picture P5 shown in fig. 8, i.e., the second state of the display system 1200. The two examples described hereinafter will be continued with the two examples described above and are incorporated by reference.

For example, N is now the 10 th row of gate lines damaged, and the total number of gate lines M is 720. The in-vehicle system 1100 will evaluate the display condition of the first display 1220, and the in-vehicle system 1100 will generate the control signal and control the gate driving circuit GOA1 through the timing controller 1210 to change the driving mode direction, which is driven from the 720th gate line 720th GL to the 11th gate line 11th GL from bottom to top.

For example, N is currently the 10 th to 20th rows of gate lines damaged, and the total number of gate lines M is 720. The in-vehicle system 1100 will evaluate the display condition of the first display 1220, and the in-vehicle system 1100 will generate the control signal and control the gate driving circuit GOA1 through the timing controller 1210 to change the driving mode direction, which is scanned from the 720th gate line 720th GL to the 21 st gate line 21th GL.

In summary, the in-vehicle system 1100 evaluates the display condition of the first display 1220 to drive the gate driving circuit GOA1 and the gate lines based on displaying larger frames through more gate lines.

In some embodiments, referring to fig. 6, 8 and 9, the signal timing diagram of fig. 9 only includes the signal U2D and the signal D2U more than that of fig. 6. The signal U2D and the signal D2U are two signals for changing the driving direction in the driving mode.

In step 242, the display frame of the vehicle display is transferred to another display of the vehicle.

In some embodiments, referring to fig. 1, fig. 2, fig. 3, fig. 10A and fig. 10B together, fig. 3 shows a first state of the display system 1200 being a normal display state. In comparison with fig. 3, fig. 10A shows a first state of the display system 1200 being a state showing an abnormality. In detail, fig. 10A shows the first display 1220 of the display system 1200 in a display abnormal state. More specifically, when the on-board system 1100 evaluates that the first status of the display system 1200 is at a predetermined level (e.g., a moderate damage level) according to the error detection signal, the on-board system 1100 further evaluates whether the first display 1220 is enough to display the display screen P6. If the first display 1220 is enough to display the display image P6, the display image P6 is zoomed, and the detailed steps are already described in the embodiment of FIG. 5 and will not be described herein. Fig. 10B shows the second display 1230 of the display system 1200 in a normal display state. The second display 1230 is used for displaying a display image P7.

In some embodiments, referring to FIG. 10A, FIG. 10B, FIG. 11A and FIG. 11B, if the first display 1220 is not enough to display the display image P6, the in-vehicle system 1100 outputs a control signal to transfer the display image P6 to one of the plurality of second displays (e.g., the second display 1230). While the embodiment of fig. 11A presents a display P8, i.e., no display, for the first display 1220. In the embodiment of fig. 11B, the display image P6 of the first display 1220 of fig. 10A is shifted to the second display 1220. The second display 1220 presents a display screen P9. It should be noted that the size of the display P9 is limited by the size of the second display, and may or may not be different from the display P6. Fig. 11A and 11B show a second state of the display system 1200.

In some embodiments, step 241 or step 242 may be repeated.

In step 243, the driving information of the vehicle or the sound effect of the warning signal is played. In some embodiments, referring to fig. 1, when all displays in the vehicle cannot display the driving information of the vehicle, the on-board system 1100 is configured to play a plurality of driving information of the vehicle or sound effects of the warning signal when the first state of the display system 1200 is evaluated as a predetermined level (e.g., a severe damage level) according to the error detection signal by the on-board system 1100. For example, the vehicle system 1100 will play the following sentence through the sound processor or speaker, wherein the speed per hour of the present vehicle is 90 and the vehicle cannot display the driving information, and if the speed exceeds the speed limit, the vehicle will slow down, or the vehicle cannot display the driving information and drive to the roadside or the shoulder of the highway.

In step 250, the display is normal.

According to the foregoing embodiments, a fault detection method and a vehicle-mounted display fault detection system are provided to enable a driver to receive driving information while different display panels of the vehicle are broken.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
